WILLIAM ANTHONY JONES, OF WEST NEW BRIGHTON, NEW YORK.

MECHANICAL MOVEMENT.

original application filed May 25, 1908,

To all whom it may concern:

Be it known that I, \VILLIAM ANTHONY Jones, a citizen of the United States, and resident of- WVest New Brighton, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification.

My invention relates to engines and pumps in which there are a number of cylinders arranged around a central-shaft to which their axes are parallel and more particularly to the transmission mechanism for converting the reciprocating motion of the pistons in the cylinders into the rotative motion of the central shaft or vice versa.

The mechanism is very compact, admits of a multiplicity of cylinders being applied to one shaft, avoids excessive lateral pressure from the pistons to the cylinders as is frequently the case with/crank engines and the consequent wear and leakage of the pistons. Expensive crank forgings are avoided, and the pistons may be readily taken out and replaced. In the accompanying drawings Figure 1 is a part longitudinal section of an engine which illustrates my invention. Fig. 2 shows a section on the line A A of the engine shown in Fig.1. Fig. 3'shows a View of the disk. Fig. 4 is a detail view of the disk restraining piece. Fig. '5 is a part longitudinal sectlon of an engine showing another form of my invention. Fig. 6 shows a section on the line B B of Fig. 5. Fig. 7 is a detail 'view of the disk shown in Fig. 5. Fig. 8 is a view of the disk restraining piece shown in Fig. 5. Figs. 9 and 10 are detail views to a large scale of the connecting rods with nuts and pins shown in Figs. 5 and 11. Fig. 11 shows a slight modification of the mechanism shown in Fig. 5. Fig. 12 is a view of the disk bearing piece,the disk, an

intermediate piece and a connecting rod similar to those shown in Fig. 5, except that the bearing between the pins of the'disk and the intermediate pieces are cylindrical.

Fig. 13' is a view of a piece of the disk,-

shown in Fig. 12, looking parallel to the axis of the bearing between the disk and the disk bearing piece. Fig. 14-is a view looking parallel to the axis of the cylindrical bearing between oneof the projecting pins of the disk and the intermediate piece and Specification of Letters Patent;

shows the intermediate piece and its connection to the rod and to. the disk.

Similarparts are referred to by similar letters throughout the several views.

Referring to the drawings, a central shaft, a, is surrounded by a casting, b, of five cylinders in which pistons, c, are fitted. The pistons, 0, are connectedby the rods, 0, to thewabbler disk, f, which has a bearing on a disk bearingpiece or oblique crank, g, and is restrained from rotating by a disk restraining piece, 2', whose internally projecting trunnions, h, engage the disk, f, and

Whose externally projecting trunnions, j,

are held in fixed bearings,'k. The disk bearing piece, g, is adapted to revolve with the central shaft about the same axis. The axis of the bearing between the diskgj. and the disk bearing piece, 9, is oblique to the axis of the central shaft, a, so that as the central shaft and the disk hearing picce revolve the plane of the disk, f, is constantly changing and the pistons reciprocate in their cylinders.

The bearing between the disk, disk bearing piece, 9, is shown formed of a single line of large steel balls, I, retained in a suitable groove in each of the two pieces. For convenience in assembling the pieces of this hearing the disk may be formed of two pieces as shown in Fig. l or the disk bearing piece may be divided into two pieces as shown in Fig. In either case the component parts of the divided piece are boltedtogether to act at one piece after the hearing has been put together. The connections between the connecting rods, 6, and the disk, f, may be universal joints formed of ball and socket joints as shown in Fig. 1 or may be universal joints each formed of two bearings whose axes are approximately at right angles to each other as shown in Figs. 5 and 11..

f, and the i 1 In Figs. 5 and 11 the disk f, is shownh with radialscrews, p, projecting from its edge on which are fitted nuts I to which the connecting rods, e, are joined by the pins, 1.

on said threaded pins and also pivotally con nected-to the rods, so as to form universal couplings or joints between the rods and disk.

3. A rotary member having a peripheral groove with its geometrical axis oblique to its axis of rotation, balls in the roove, a

disk having an. internal groove w ich embraces the balls and forms a bearing with them, pinsw projecting from the disk, a ring having external trunnions adapted to be mounted in fixed bearings, and internal trunnions engaging the disk, a plurality of rods connected to the disk, the connection between the rods and disk comprising intermediate pieces pivotally mounted on said pins and'also pivot-ally connected to the rods, so as to form universal couplings or joints between the rods and disk.

4. A rotary member having a peripheral groove with its geometrical axis oblique to its axis of rotation, balls in the disk having an internal groove w ich embraces the balls and forms a bearing with them, a ring having external trunnions adapted to be mounted in fixed bearings, and internal trunnions engaging the disk, a plurality of rods connected to the disk, the conne ction between the rods and disk comprising intermediate pieces pivotally connected to said disk, and also pivotally connected to the rods, so as to form universal couplings or joints between therods and disk. 5. A rotary member having a peripheral oove with its geometrical axis oblique .to its axis of rotation, a disk mounted on said member and in engagement with said groove, a ring adapted to be pivotally mounted in fixed bearings; and also pivotally connected to the disk on a .line transversal connections with the disk.

' 6. Two alinedfshafts,an oblique crank oove, a

casing being split transversely thereof at aplane adjacent to the center of symmetry of the disk and crank.

7. A rotary member having an oblique crank, a wabbler disk mounted on said crank and restrained from rotating therewith, threaded pins projecting from the disk, and rods connected to the disk, the connections between the rods and disk comprising intermediate pieces mounted on said pins and pivotally connected to said rods, the threads of said pins serving to retain the intermediate pieces from disengagement.

8. A rotary member having a peripheral groove with its geometrical axis oblique to its axis of rotation, a disk having an internal groove and a single row of balls forming an antifriction bearing between said grooves, rods connected to the disk, and means for restraining the disk from rotating with the rotary member. y

9. A shaft, an. oblique crank mounted thereon and connected to rotate therewith, combined thrust and lateral bearings at both ends of the crank, a stationary member through which'the shaftpasses, and two from strains due to the bending movements exerted by the oblique crank.

A Signed at West New Brighton in the county of Richmond and State of New York this eighth day of April A. D. 1909.

WILLIAM ANTHONY JONES.
